A while back, I asked a question about defragging a SSD. I was told that I should not try to use the Windows Defrag tool because a SSD could be damaged by it because of the architecture of the SSDs internal workings.
This leads me to ask about using a program like Eraser which erases files, or an entire disk, by overwriting the data tracks several times. But since the SSD doesn't have tracks, I'm wondering if a Program like Eraser will work on the SSD or might even cause problems.
Is just deleting a file sufficient to make it inaccessible to someone trying to re-access the file in the future? And what about trying to retrieve a file that was deleted accidentally? In other words, when a file is deleted from a SSD, is it really gone forever?
